Please refer to Fig. 1 to Fig. 8 in combination. These drawings only schematically show the main components of an embodiment of a vehicle-mounted dual-mode integrated seat according to the present invention and its functions in different working modes or configurations. situation, which will be described in detail below.

As shown in FIG. 1 and FIG. 2 , in this given embodiment, the vehicle-mounted dual-mode integrated seat 1 is integrated with two common vehicle-mounted seats in a centrally arranged manner inside the vehicle. For example, the seats may preferably be arranged as the last row of seats in the vehicle so that they are adjacent to and fully utilize the space in the trunk of the vehicle, as will be described later.

The vehicle-mounted dual-mode integrated seat 1 includes a seat part 3 and a back part 4, the former is suitable for being installed in the vehicle for providing the occupant to ride, while the latter is provided with two back parts, that is, the first back part 5 and the second backrest part 6, which are arranged opposite to each other. In the present utility model, the above-mentioned backrest 4 is innovatively constructed so that it can rotate in all directions up to 360° around its longitudinal axis X (Fig. 3). Select the toggle to provide two completely different ride modes, a first ride mode for adults (as shown in Figures 1 and 2), and a second ride mode for children (as shown in Figure 4 and Figure 5). It should be pointed out here that the term "children" in this article should have a broad meaning, which needs to fully take into account such as individual growth and development lag, and should not be simply understood as being limited by a specific age range.

Specifically, in this embodiment, Fig. 1 and Fig. 2 schematically show the front structure and the back structure when the vehicle-mounted dual-mode integrated seat 1 is in the first riding mode. At this time, the backrest 4 of the vehicle-mounted dual-mode integrated seat 1 is rotated so as to expose the first backrest 5, so that the first backrest 5 and the seat 3 together constitute a seat for an adult. The seat to take, that is, the standard seat that is usually configured in the car, the seat at this time conforms to the normal sitting posture and posture use standard of ordinary adults, and this seat can be used together with other conventional seats 2 to meet the daily riding of passengers such as ordinary adults need. It can be understood that, in the first riding mode, the second backrest part 6 opposite to the first backrest part 5 in the present utility model is actually deliberately placed in an unexposed state, that is, the second backrest part 6 At this time, it is located in the space where the backs of the above-mentioned seats are located. Such space can be a part of the trunk of the vehicle, that is to say, a part or all of the second backrest part 6 can be accommodated in the trunk of the vehicle. As a result, the utilization of interior space and trunk space can be considerably improved.

Fig. 4 and Fig. 5 schematically show the front structure and the back structure respectively when the vehicle-mounted dual-mode integrated seat 1 is in the second riding mode. In the second sitting mode, the backrest 4 is rotated to expose the second backrest portion 6 of the backrest 4, thereby providing a child seat.

However, in some embodiments, the present invention also allows the above-mentioned positioning device not to be centrally arranged, but to deviate from the central longitudinal axis of the backrest 4, so as to meet the actual application requirements in some specific situations.

For the rotary yoke device, its first yoke 18 and second yoke 19 are all arranged on the backrest 4, so that after the backrest 4 is rotated in place, the backrest 4 and the backrest 4 can be connected together. The relative position between the two seating parts 3 is fixed so as to thereby provide the above-mentioned first riding mode or second riding mode. According to actual application conditions, it may be considered to set three or more yokes in the above-mentioned rotary yoke device. Moreover, the specific arrangement positions, materials and shape configurations of the yokes in the rotary yoke device can be flexibly selected and adjusted according to actual conditions. Furthermore, by way of example, one or more of the yokes in the swivel yoke arrangement may be configured as shown in FIG. 18'', 19'', so that the backrest part 4 is lifted in the longitudinal direction along the arrow A shown in Fig. and the fork arm lower part 19'' are disengaged from each other, thereby making the backrest part 4 break away from the original fixed position, and then the backrest part 4 is rotated in place along the arrow B in Fig. 3, and then the The upper part 18' of the yoke and the lower part 19'' of the yoke, and the upper part 19' of the yoke and the lower part 18'' of the yoke are respectively engaged at the new position, so that the relative displacement between the backrest part 4 and the seat part 3 can be limited , thus it can be simply and effectively guaranteed that the vehicle-mounted dual-mode integrated seat 1 can be in the first riding mode or the second riding mode as expected.
